Feature Store
A Feature Store is a machine learning infrastructure component for unified management, storage, and sharing of feature data. Its primary purpose is to eliminate training-serving skew—inconsistencies between features used during model training and those served in production—while improving feature reuse efficiency across teams and projects.

Extending ChurnWatch can introduce Amazon SageMaker Model Monitor for automatic drift detection, use SageMaker Pipelines to orchestrate the retraining process, and use Feature Store to unify feature definitions, thereby connecting detected drift to a closed loop of automatically triggered retraining.
The mainstream solution to the feature consistency problem is to establish a unified Feature Store, allowing offline and online systems to share the same set of feature definitions and computation logic.
Feature Stores address the problem of inconsistency between feature computation during training and inference, and are a critical component of production system reliability.
Feature stores such as Feast or Databricks Feature Store can resolve the inconsistency between features used during training and features used during online inference.
A Feature Store is used to uniformly manage online and offline features, avoiding training-serving skew.
A Feature Store is a centralized feature management platform that solves the problems of feature consistency and reusability, with representative products including Feast and Tecton.
Without a Feature Store, the features used in online inference and offline training may diverge, resulting in training-serving skew.
The core design philosophy of Feature Store is 'Write Once, Use Everywhere,' where feature computation logic is defined only once and converted by the platform into both batch processing and real-time computation execution modes.
The concept of Feature Store first entered public awareness in 2017 when Uber published a technical blog post about its internal platform Michelangelo.
Introducing a unified Feature Store that allows training and serving to share the same feature definitions and computation logic is a common method for resolving training/serving skew.
